Most of the time when i play out of the bunker with the cleveland 64 degree wedge, i always use full backspin, but its like spin doesn't work. The ball rolls for miles. This never used to happen with the zatin, ball would stop quite well, but its like the clevelands dont register spin when playing from bunker. You might be lucky and get 1 bunker shot out of 10 that does actually slow down, but usualy ball will roll for miles down the green.
